Gorge is a narrow valley with very steep sides, often deeper and tighter than a canyon. It is usually formed by fast-moving rivers cutting through rock. Gorges can have cliffs on both sides and a river flowing at the bottom. They are often difficult to cross.

Gorges are found in mountainous or river regions around the world, including parts of Europe, Asia, and Africa. They formed over long periods of time. Gorges may contain rivers and support plant and animal life. Human access can be limited due to the steep terrain.
